A business researcher has to decide which of three employees should be placed in a particular job that requires a high level of perceptualmotor coordination. All three employees have taken tests of perceptualmotor coordination, but each took a different test.
Employee A scored 15 on a test with a mean of 10 and a standard deviation of 2.
Employee B scored 350 on a test with a mean of 300 and a standard deviation of 40.
Employee C scored 108 on a test with a mean of 100 and a standard deviation of 16.
On all three tests, higher scores mean greater coordination.
Which employee has the best perceptualâ€“motor coordination?

Z = (scoremean)/SD
Which has the highest Z score?
